If you are using it for gaming I wouldn't get the FX-8150 as it is easily outmatched by the Intel counterparts. Save some money on the processor, get an i3-2120, and spend it on your graphics card and get a GTX 560 ti or a Radeon HD 6950.
What are your goals?
What is your budget?
What resolution is your monitor(s)?
However even without knowing that I don't recommend the AMD FX-8150. It is not a very efficient processor. The Intel Ivy Bridge Core I-5 is FAR better and is definitely worth the extra $20. It makes a huge difference in gaming.
